DESCRIPTION OF PROGRAM :- 

Starting calculation please 
click here 
01421- Name of program
N10- Tool change command , select tool no. 3
N30- Coolant ON
N20- Spindle ON anti-clockwise ( for RH thread) , constant speed command , speed is 1000 rpm
N40- Rapid action command , where X50 and Z2
N50- Threading cycle command , P01 - no of finish path
                                                               00 - chamfer amount is 00mm
                                                               60- angle of tool tip ,
                                                       Q100- each cut is 0.1 mm ,
                                                       R20- finishing allowance 0.02 mm 
N60- Threading cycle command , X45 is end diameter , tool threading upto -55 in Z axis , P thread depth 1.227mm , depth of finish cut is 0.2 mm , R taper thread parameter is 10.5 , F is pitch is 2.
   
P Depth  of thread = pitch x 0.6136 = 2 X 0.6136 = 1.227 mm = 1227 in micron 
R taper thread parameter = ( end dia. - start dia ) / 2 = (45-24) / 2 = 10.5

N70- Rapid action command , where X50 and Z2
N80- Spindle OFF , coolant OFF , main prog. end .
